For determining the crushing properties of bulk aggregate applying 400 kN load over a period of 10 minutes.
ASTM C-29 / AASHTO T-19 For determining bulk density of fine, coarse or mix aggregate. Manufactured from heavy duty gauge steel these bulk density measures comply with the requirement of either BS812 or ASTM C29. Other than the 3 litre size all measures incorporate carrying handles as standard.
ASTM C-128 / AASHTO T-84 For determining the water absorption of fine aggregate at saturated surface dry. The equipment is supplied complete and ready to operate with a cone, tamper, mixing bowl, glass plate, spatula and volumetric flask 500 ml capacity.
ASTM C-127 / AASHTO T-85 For determining specific gravity and water absorption of coarse aggregate. A mechanical lifting device is used to raise the water tank through the frame height immersing the speciment suspended below the balance. Consist essentially of a wire basket, water container and heavy duty balance 20 kg capacity.
ASTM C-127 / AASHTO T-85 For determining specific gravity and water absorption of coarse aggregate. The equipment is supplied complete and ready to operate with a wire basket, 20 ltr water container cpacity and digital balan balance 6100 gr x 0.01 gr capacity .
ASTM C-40 / AASHTO T-21 For an approximate determination of organic compound in sand. Ordering information.
ASTM C-88 / AASHTO T-104 For determining aggregate resistance to desintegration by saturated solution of sodium sulfate or magnesium sulfate. Ordering Information
The Void Content Apparatus is used to determine the uncompacted void content of a fine aggregate sample. The method indicates the angularity, sphericity, and workability of fine aggregate in a mixture for which it may be used. Each sample is mixed with a spatula until it is homogeneous. After filing the hopper, the sample is allowed to flow into the 100ml cylindrical measure. The measure has a locating hole to fit a lug on the Funnel Stand to ensure each sample is tested with precesion and repeatability. Once the user strikes off excess material, mass in determined and void content is computed. Pan as a sample retainer Included with the 100ml copper Cylindrical Measure. Funnel with specified hopper. Funnel Stand and a Glass Plate to calibration.
The strength of rock is an important property which may measured in a number of ways. Point-load strength testing is particulary useful tes method which can be perfomed on specimens requiring little oor no preparation prior to testing. The test can perfomed on site or in the laboratory with variations such as the diametral test, the block test and the irregular lump test. Other application include the determination on site of a strength index for concrete and the prediction of cube strength from point load index.
